New Method for Preparation Of Azo Compounds and Study of Its complexes with Cu+2, Zn+2, Cd+2 and Hg+2


New method to prepare 4,4-Azodibenzoic acid with the ligand was identified by FT-IR and UV-Vis spectroscopic technique. Treatment of the ligand with the following metal ions (Cu+2, Zn+2, Cd4 Hg+2)in aqueous ethanol with a 2:1 metal:ligand. The prepared complexes were characterized using flame atomic absorption, FT-IR and UV-Vis spectroscopic methods as well as magnetic susceptibility and conductivity measurements.
